When using CBR rate control and configuring AverageBitrate = 300Kbps I get an encoded bitrate around 100kbps if the video is not very dynamic. If the video is very dynamic the encoded bitrate ends up around the expected 300kbps.
The same happens with other higher bitrates but in low bitrates the issue is especially problematic for my use case.
Is there any way to configure the encoder to provide a bitrate closer to the expected one even when the video is not changing that much?
Thank you very much
